Well, they don't give any real info on shipping costs to Austria, and I'm afraid I wouldn't want to hear the answer. Remember, I'm going there for 1 week. Considering my short hair I'll probably use my dryer twice. By now it's not clear if I'll really go there (still have to check with 4 classmates of mine + other hassles including dealing with eyp (european youth parliament) uk), and I HAVE that adaptor. (And there are dozens of _unfused_ UK travel adaptors around!), so maybe I'll just stick to C-H's suggestion, i.e leave the foil as is. A short will pretty sure trip a 32A breaker as well, overload is pretty unlikely here. Plus if we stay with host families either they have a hairdryer or I can plug mine into a fused power strip.
Anyway, if I buy anything I'll decide on that later on.
Thanks for your input.
